Abstract

Extremely small parameter perturbations via self-interactions of chaotic signals can smoothly change chaotic Lorenz system to a series of dynamics such as distorted attractors, tori, limit cycles, or simple fixed points. Brand-new dynamics can also be obtained due to the generation of new fixed points. It is shown that the above dramatic changes in dynamics are due to exchanges of stabilities of fixed points although they are slightly perturbed.

    Chaos has also been extensively studied in many fields, such as chemical reactions, power converters, biological systems, information processing, secure communications, etc. [1–9]. Since E.N. Lorenz [10] discovered chaos in a simple system of three autonomous ordinary differential equations in 1963 (called contemporary Lorenz system in this Letter), there are lots of articles in studying contemporary Lorenz system [11–15]. Although the contemporary Lorenz system has been analyzed in detail, there are no articles in looking into the historical Lorenz system.
